Known Issues

Web version

The Web version works okay for the most part.

1. Embedded Youtube videos don't work in app (see the flutter_widget_from_html package).

   • As a workaround for this issue, the app simply opens the Youtube video in a new tab. (link to relevant commit)

2. Cached network images don't work (see the cached_network_image package).

   • Update 2020-07-19: Reverting back to local images to fix this. (link to relevant commit)

App layout

There is an issue with the PageController going beyond the last page when the LayoutBuilder switches from vertical to horizontal layout. This might be a bug concerning the use of CustomScrollView under a PageView, I'm not exactly sure. It may be worth checking out the SliverLayoutBuilder class.

UPDATE: It seems other people have been having the same issue. See issue #61156.

FIXED Embedded Youtube video (Android)

The audio from the embedded Youtube video persists if the app is not closed and the user decides to go out of the app or turns off their display. I figure this may be more of a feature than a bug, though, potentially allowing for Youtube streaming without ads.

UPDATE: Switching to the youtube_player_flutter package, this is no longer an issue. (relevant commit)

WARNING: There is something SEVERELY wrong with the embedded Youtube videos that cause the Android device to be COMPLETELY borked. I'm trying to fix this ASAP.

UPDATE: Added WAKE_LOCK permissions by adding <uses-permission android:name="android.permission.WAKE_LOCK"/> to the AndroidManifest.xml (link to relevant commit). Hopefully this should fix the issue above. See https://developer.android.com/reference/android/os/PowerManager for more details. NOTE from the Android Developers documentation:

Device battery life will be significantly affected by the use of this API.
